This is the updated version of the previous bobble hat pattern with more in depth instruction and customization options. This pattern is a made to measure, bottom up hat pattern. It uses textured stitches like the bobble stitch, half double crochet in third loop, and single crochet back loop only. There are video tutorial links included in the pattern. It can be made with or without a folded brim and can be modified to the desired length and width. My measurements are included in the pattern for reference but it can easily be modified to your head size. I used 250 yards of red heart super saver solids.
